From Charge Storage Rulebook Rewriting to Commercial Viability of Zinc‐Manganese Batteries

open access: yesAdvanced Science, EarlyView.
The Mn3O4 cathode undergoes a partially in situ phase transition to MnO2 during the initial charging process, forming a hybrid Mn3O4/MnO2 cathode. The Mn3O4 provides a robust supporting structure for MnO2 to enhance the cathode stability upon H+/Zn2+ co‐insertion/extraction.

Scandium Induced Structural Disorder and Vacancy Engineering in Li3Sb – Superior Ionic Conductivity in Li3−3xScxSb

open access: yesAdvanced Energy Materials, EarlyView.
A superionic conductivity of 42 mS cm−1 at 298 K is reported for Li2.55Sc0.15Sb, which exceeds the highest ionic conductivity reported for a solid Li‐ion conductor to date by 10 mS cm−1. In the series Li3−3xScxSb (0 < x ≤ 0.15), the gradual incorporation of Sc facilitates vacancy formation, converting pristine Li3Sb from an electrical to an ionic ...

Enhancing Specific Energy and Cycling Stability of High‐Temperature Na‐ZnCl2 Batteries with Foam‐Based Electrodes

open access: yesAdvanced Energy Materials, EarlyView.
Replacing nickel with zinc in high‐temperature sodium‐zinc chloride (Na‐ZnCl₂) batteries makes them more cost‐effective and sustainable. Foam‐based Zn/NaCl electrodes enable substantially increased metal utilization compared to granule‐based electrodes (66% vs 30%).
